Cassandra：未定义的列名权限

Question

Cassandra 抛出异常：

com.datastax.driver.core.exceptions.InvalidQueryException: Undefined column name permissions at com.datastax.driver.core.exceptions.InvalidQueryException.copy (InvalidQueryException.java:50) at com.datastax.driver.core.DriverThrowables.propagateCause (DriverThrowables.java:37) at com.datastax.driver.core.AbstractSession.prepare (AbstractSession.java:100) at org.accells.connection.CassandraSession.prepare(CassandraSession.java:120)

很遗憾，我在网上找不到任何关于此的信息。请指教。抛出这个异常的那一行是cassandra代码：

/**
 * Prepares the provided query string.
 *
 * @param query the CQL query string to prepare
 * @return the prepared statement corresponding to {@code query}.
 * @throws NoHostAvailableException if no host in the cluster can be
 *                                  contacted successfully to prepare this query.
 */
PreparedStatement prepare(String query);

提供的查询是 SQL 个有效查询。

Answer 1

此错误告诉您 permissions 列在您尝试查询的 table 中不存在。

来自这里：

ColumnDefinition def = cfm.getColumnDefinition(id);
if (def == null)
    throw new InvalidRequestException(String.format("Undefined column name %s", toString()));
return def;

在ColumnDefinition.java中（因为不知道你是什么版本所以没有链接代码运行。
